SENSITIVE-MATERIAL UNIT.

Application filed March 8, 1923. Serial No. 623,588.

To all whom it may concern:

Be it known that I, EDWARD P. FLYNN, a citizen of the United States ofAmerica, residing at Rochester, in the county of Monroe and State of NewYork, have invented certain new and useful Improvements inSensitive-Material Units, of which the following is a full, clear, andexact specification.

This invention relates to a sensitized material unit adapted for use ina commercial copying camera. The sensitized material for use in suchcameras generally consists of heavy, cumbersome rolls of paper to be.placed in the camera. Enough paper is drawn from this storage roll for asingle exposure at a time and this is then severed and passed todeveloping and fixing baths.

Among the objects of my invention are to provide a unit which may beloaded into the camera, to provide means for centering the roll' ofpaper in such a unit prior to its being placed in the camera, to furnishautomatic means for such centering and for closing the unit and toprovide means whereby the paper remaining at any time may be removed ina protected container if it is desired to clean or repair the machine.Other objects will appear hereinafter.

Reference will now be made to the accompanying drawings, in which thesame referencecharacters refer to the same parts throughout and inwhich- Fig. 1 is a perspective view of the box of my improved unit;

Fig. 2 is a section taken on line 11-11 of Fig. 1 the cover not beingshown;

Fig. 3 is a section taken on line IIl-III of Fig. 1, the cover not beingshown and the roll being indicated in dotted lines;

Fig. 4 shows the latch in detail;

Fig. 5 "is a perspective view of the roll of sensitive material;

Fig. 6 is a section through the unit as used in a copying camera,certain parts of which are indicated in dotted lines Fig. 7 is afragmentary view, partly in section, illustrating the action when thebox is being closed;

Fig. 8 is a fragmentary plan of one end of the box.

My new and improved unit comprises two essential elements, a box orcontainer 1 and a package 2 containing the sensitized material. The boxis of sheet metal and has a fixed bottom 3, fixed side walls 4 and 5, afixed end wall 6 and a hinged end wall 7. In the fixed end wall 6 is aninwardly extending circular trunnion member 8 comprising an imperforatebottom 9, an inclined side wall 10 and an annular flange 11 by which itis secured in any suitable way in the rabbet 12 surrounding a centralaperture 13 of the wall.. The wall? is hinged at 14, as shown, and has atrunnion member 15 identical instructure to that already described, theparts being similarly designated. The wall 7 carries near the upper endsof its side edges two angle brackets 16 to which-are pivoted at 17 thelatch members 18 having inclined faces 19 and notches 20. On the innerfaces of side walls 4 and 5 are pins 21, which are engaged by thelatches in an obvious way when the hinged end is closed. The latches maybe lifted to the inoperative position indicated in dotted .lines in Fig.4 when the end is to be opened.

It is to be noted that side wall 4 is lower than wall5 for a purpose tobe presently described. Finger rings 22 are provided on wall 4 for apurpose to be later mentioned. A removable cover 23 with flanges :24that fit tightly around the sides of the box is also provided.

For the purposes of the present invention the package 2 of sensitivematerial is a cylinder with inwardly tapered axial openings in itsend.'the particular structure of the cylinder being comparativelyunimportant. As shown, it comprises a roll of sensitive paper 25. theouter end of which is tapered at 26 and secured bya'wrapper strip 27.End members comprise flanges 28 with reinforced edges 29 and centralhubs 30. The

hubs are hollow and imperforate and taper inwardly and engage the innerconvolutions of paper frictionally in a manner similar to that describedin my Patent No. 1,377,154, granted May 3, 1921. They provide, end axialapertures with tapered walls for the package 2.

In practice, while the boxes may be furnished with the sensitivematerial, they will in general be supplied ,with the copying cameras forwhich they are adapted and the same box will be used with successiverolls of material. The cover is not used in the camera and is suppliedso that if it is desired to remove theunit from the machine positionshown, the several parts describing the arcs indicated. The inner end ofthe trunnion member will just engage the outer edge of the hub aperture,and as both hub and trunnion have correspondingly tapered side walls,further inward movement of the wall 7 will exert a caniming actionbetween these two elei'ncnts to lift the end of the package 2 to aproperly centered position in the box. The latches will automaticallyoperate to hold the wall in its final position.

The unit comprising the box and the roll is then ready for insertion inthe copying camera. The details of such a camera are not shown, as theyconstitute no part of the present invention. In Fig. 6, however, thereare indicated certain elements showing how the unit is used. The cameraincludes a cabinet having a rear wall 31, a top wall 32 and a shelf 33within which the unit is shoved from the left of Fig. 6, with the lowerside wall 4: outwardly. The end of the paper is drawn out and a wall 34having a guide roll 35 placed in the position shown. With the parts inthese relative positions the paper is withdrawn and used as needed. Nocentering and positioning of the heavy roll in the camera is required,all of this being done inthe unit before its insertion in thecompartment provided for it.

When the paper is exhausted, the wall 3i is removed and the unitwithdrawn by the. finger rings 22. I

lit will thus be seen that T have provided means whereby the heaw yrolls of material are easily positioned and handled. 1 con template aswithin the scope of my invention all such modifications and equivalentsas fall within the terms of the appended claims.

Having thus described my invention, what T claim as new and desire tosecure by Letters Patent is:

l. Tn combination, a roll of sensitized material having end hubs withcentral apertures, and a box adapted to contain said roll and having afixed end wall with a fixed trunnion engaging one end aperture, andhaving an opposite hinged wall, said hinged wall having a trunnionadapted to engage the opposite end aperture, the last named trunnion andthe corresponding aperture being so shaped that when the wall is swungto closed position these parts will engage with a camming action andlift the roll to properly centered position in the box.

2. A. unit adapted to be placed in a commercial copying camera andcomprising a cylindrical package of rolled sensitized material, and abox adapted to fit and contain said package, said box having a fixedend, said end and one end of the package having means cooperating 'toposition and support the package, said box having a hinged end, saidhinged end and the opposite end of the package having cooperating meansfor lifting said end of the package to properly centered position as thehinged end is moved to closed position, and for supporting the packagein such properly centered position when it is in closed position.
